Field of values — In matrix theory, the field of values associated with a matrix is the image of the unit sphere under the quadratic form induced by the matrix. More precisely, suppose A is a square matrix with complex entries. The field of values for A is the set … Wikipedia
Field (mathematics) — This article is about fields in algebra. For fields in geometry, see Vector field. For other uses, see Field (disambiguation). In abstract algebra, a field is a commutative ring whose nonzero elements form a group under multiplication. As such it … Wikipedia

Commuting matrices — In linear algebra, a set of matrices is said to commute if they commute pairwise, meaning AiAj = AjAi for every pair i, j (equivalently, the commutator vanishes: [Ai,Aj]; more abstractly, if the algebra they generate is an abelian Lie… … Wikipedia
Block Lanczos algorithm for nullspace of a matrix over a finite field — The Block Lanczos algorithm for nullspace of a matrix over a finite field is a procedure for finding the nullspace of a matrix using only multiplication of the matrix by long, thin matrices. These long, thin matrices are considered as vectors of… … Wikipedia
2 × 2 real matrices — The set of 2 × 2 real matrices is denoted by M(2, R). Two matrices p and q in M(2, R) have a sum p + q given by matrix addition. The product matrix p q is formed from the dot product of the rows and columns of its factors… … Wikipedia
Real matrices (2 x 2) — The 2 x 2 real matrices are the linear mappings of the Cartesian coordinate system into itself by the rule:(x,y) mapsto (x,y)egin{pmatrix}a c b dend{pmatrix} = (ax + by, cx + dy).The set of all such real matrices is denoted by M(2,R). Two… … Wikipedia
